The article stresses the consequences of simplifications implemented in the measurement process of goods produced that are of crucial importance to production engineers in SME. The authors show the variety of possibilities that might be used by financial employees together with probable outputs in terms of valuation distortions. Using the case study the authors emphasis the importance of close cooperation of production engineers with finance professionals as out-puts of finance departments consist an important input for decision-making process of production managers. Further-more, demonstrated deficiencies in terms of methods applicable in financial reporting for measurement of the value of goods produced indicate the need for incorporation more financial and non-financial data in the process of judgments about the final cost of goods produced as simplifications applied in SME distort financial information provided to production engineers.
